Similarly, we repeated the temperature t = 5,7,9,11, respectively, the above experiment, the results are as follows: u = a 1.6381410e--8 +8.3592210 e - 6v +0.641737 v-2. t = 5u = 1.638410e an 8 +8.3604310 e a a 6v +0.89882 v'2. t = 7u = a 1.6385510e--8 +8.3610910 e - 6v +1.1559 v'2. t = 9u = a 1.6386410e--8 +8.3615210 e - 6v +1.41299 v'2. t = 11 on the above results of numerical analysis, we found that if you do not count the experimental error, in the low frequency of blackbody radiation law can be expressed as u = A (t) v ~ 2 where the coefficients A (t) the temperature t of the function, after curve fitting of the temperature t, we get A (t) = 0.128422t, combined with the style we finally got the experience of low frequency blackbody radiation formula u = 0.128422tv2 the result of a Hopkins and Rayleigh introduced the theoretical formula exactly the same. 3 full-band numerical simulations carried out below is our full-band numerical simulation of black-body radiation experiments. We first numerical simulation results based on an interpolation function constructed from the interpolation function of the image can be seen when the temperature t must have a maximum energy density, the frequency of maximum points corresponding to vm. At different temperatures. By the numerical simulation we obtained a series of maxima corresponding to the frequency of Vm (t). Then the experimental data obtained, after we finally get a fitting empirical formula vra (t) = 1.084210e 14 +5.878 t spent a post-experimental error. We get the vm (t) = 5.878t this result with the history of Wien's displacement law exactly. Here is our experiment the experimental data and curve fitting procedures. data = {{3,17.634}, {5,29.390}, {7,41.146}, {9,52.902}, {11,64.658}}; mUlTI = Fit [data, {1, t}, t] four conclusions of our numerical simulation of theoretical physics is the idea of ​​the Ministry of Education,<a href="http://www.belstaffoutlets.org" target="_blank" class="postlink">belstaff outlet</a>, based on the argument. It wants to experiment with the physical theory of mathematical thought experiment together, applied physics students of quality education. Our practice shows that this teaching method allows students to improve the processing of experimental data through experiments skills, but also to deepen the understanding of theoretical physics knowledge, but also can improve the application of computer skills.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subBlack/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
